Small Size in Living Cells
The small size in living cells can best be attributed to which of the following factors:
- the small size of most molecules
- the large number of the cells that are necessary to form an organism
- the rare favorable surface-to-value ratio of smaller cells
- the short life spans of large animals

The third statement would be the most accurate but I believe you meant to say the surface-to-volume ratio.
The size of cells can be quite variable and depend to a great deal on the function that they have within the body or in development.
For example the yolk of a bird egg is actually a whole cell and some neurons can be many centimeters long. The limit to the ...
Solution Summary
The small size in living cells is examined. The large number of the cells that are necessary to form an organism are determined.
BioMEMS - The business case for going small
Assignment for the BioMEMS - The business case for going small
The assignment should contain the following parts:
(i) Description of the present situation, with clear representation of all economic and technical variables, as well as their values for the base scenario.
(ii) Proposed new scenario, with clear statement as to what are the aims, e.g. decrease the analysis time, decrease the cost, etc.
(iii) Technical description of the new methodology, e.g. microarray, microplates, etc.
(iv) Comparison of the two scenarios; for advanced forecasters (i.e. you) one could consider a sensitivity study, e.g., more than one "dimension" - macro (present); micro (near future); nano (?).
